Revlon Colorstay eyeliner is so easy to apply as it just glides on with no mess, no breaking and definately no need for resharpening. Once applied, it can be smudged for a great smokey eye effect, although I found it a bit difficult to smudge as apposed to normal kohl liners. Lasts really long...My liner was stayed put after a long night on the town and was still there, no smudges, in the morning when I woke up!

This is a definate MUST HAVE for the make-up bag and will definately not disappoint!
